# Network Validation The Network Validation Layer (NVL) is the Raiinmaker Network’s mechanism for finalizing and securing transactions and user actions across its federated hybrid blockchain. It ensures data integrity, scalability, and trust in the decentralized ecosystem, supporting applications like AI data validation, token transactions, and decentralized identity management. The NVL leverages a Decentralized Physical Infrastructure Network (DePIN) and public blockchain checkpointing (e.g., SEI Network) to provide robust security and transparency. This guide explains the NVL’s functionality and how to participate as a validator --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
